Abstract

The invention relates to a device for use in the evaluation of suicide risk of a person. The device comprises a measuring unit (1) for measuring electrodermal activity in the fingers of the person in order to detect depressed persons who are at risk for suicide. The measuring unit is arranged to transmit a certain experimentally well defined sound signal or tone to the person and to provide a signal for the analysis of the electrodermal response from the person in question. To facilitate the analysis or increase the precision of the result of the analysis the device also comprises means for measuring orientation reactions in the form of blood volume variations of the person, preferably by means of a phtophletysmographic method peripherally in the fingers (21) and/or centrally in the frontal lobe of the brain through the forehead (22), and changes in the pulse rate of the test person.

Claims

AMENDED CLAIMS received by the International Bureau on 31 March 2015 (31.03.2015)
1. A device for use in the evaluation of suicide risk of a person comprising a measuring unit (1) that measures electrodermal activity in the fingers of the person in order to detect depressed persons who are at risk for suicide and wherein the measuring unit is arranged to transmit a certain experimentally well defined sound signal or tone to the person and to provide a signal for the analysis of the electrodermal response from the person in question, characterized in that the device, in addition to said unit (1) for measuring electrodermal activity in the fingers, also comprises means for measuring orientation reactions on sound stimuli from said sound signal or tone in the form of blood volume variations of the person as well as one or more microphones (17, 18) to detect noise interference and wherein the microphone signals are transmitted in parallel with the electrodermal response signal to be included in the signal analysis.
2. A device according to claim 1, characterized in that the measurement of the orientation reactions in the form of blood volume variations is made by means of a photophletysmographic method.
3. A device according to claim 2, c h a r a c t e r i z e d i n that the photophletysmographic method comprises a measurement of blood volume variations peripherally in the fingers (21) of the person in question.
4. A device according to claim 2, c h a r a c t e r i z e d i n that the photophletysmographic method comprises a measurement of blood volume variations centrally in the frontal lobe of the brain through the forehead (22) of the person in question.
5. A device according to claim 2, c h a r a c t e r i z e d i n that the photophletysmographic method comprises a measurement of blood volume variations peripherally in the fingers (21) as well as centrally in the frontal lobe of the brain through the forehead (22) of the person in question..
6. A device according to claim 1, characterized in that the measuring unit is arranged to transmit said sound signal or tone via headphones (2). 16
7. A device according to claim 1, characterized in that the response signal from the measuring unit is arranged to be analyzed in a laptop computer (3).
8. A device according to claim 2, characterized in that the sound signal or tone submitted by the measuring unit (1) is repeated according to a certain tested schedule in widely varying intervals, for instance around about 40 seconds, during the measurement of the electrodermal and photophletysmographic activity of the test person.
9. A device according to claim 4, characterized in that said means for measuring the orientation reactions by means of photophletysmography centrally in the frontal lobe of the brain via the forehead comprises light emitting- and sensor means arranged adjacent to the forehead (22) of the test person.
10. A device according to claim 9, c h ar ac te r i ze d i n that said light emitting- and sensor means are placed on an arm extending from the headphones up to a convenient distance from the forehead of the test person during the test procedure,
11. A device according to claim 1, characterized in that a microphone (17) is located adjacent to the upper side (4) of the measuring unit (1).
12. A device according to claim 1, characterized in that a microphone ( 18) is located adjacent to the headphones (29 and/or located on an arm extending up to a certain distance from the cheek of the test person during the test procedure.
13. A device according to claim 11, characterized by microphones located in the left and the right part of the headphones separately in order to detect audible sound, i.e. sound which reaches the eardrums of the test person and wherein the microphone signals are arranged to be sent parallel to the electrodermal response signal (10) to be included in the signal analysis.
14. A device according to claim 1, characterized by means for measuring the pulse response from the test person. 17
15. A device according to claim 14, characteri zed in that the pulse response is measured as the interval (L) between two R waves in the ECG.
16. A device according to claim 15, characteri zed i n that the pulse response is measured by an ECG amplifier.
17. A device according to claim 16, characterized in that said ECG amplifier is arranged to measure the potential difference between an electrode located between the photo emitter and - sensor on the arm extending from the headband of the headphones and the elongated electrodermal electrode (6) on the upper side (4) of the measuring unit.
